Methodology of an ongoing, randomized controlled trial to prevent falls through enhanced pharmaceutical care

A deprescribing medication program to evaluate falls in older adults: methods for a randomized pragmatic clinical trial

Background

Opioids and benzodiazepines (BZDs) are some of the most commonly prescribed medications that contribute to falls in older adults. These medications are challenging to appropriately prescribe and monitor, with little guidance on safe prescribing of these medications for older patients. Only a handful of small studies have evaluated whether reducing opioid and BZD use through deprescribing has a positive impact on outcomes. Leveraging the strengths of a large health system, we evaluated the impact of a targeted consultant pharmacist intervention to deprescribe opioids and BZDs for older adults seen in primary care practices in North Carolina.

Methods

We developed a toolkit and process for deprescribing opioids and BZDs in older adults based on a literature review and guidance from an interprofessional team of pharmacists, geriatricians, and investigators. A total of fifteen primary care practices have been randomized to receive the targeted consultant pharmacist service (n = 8) or usual care (n = 7). The intervention consists of several components: (1) weekly automated reports to identify chronic users of opioids and BZDs, (2) clinical pharmacist medication review, and (3) recommendations for deprescribing and/or alternate therapies routed to prescribers through the electronic health record. We will collect data for all patients presenting one of the primary care clinics who meet the criteria for chronic use of opioids and/or BZDs, based on their prescription order history. We will use the year prior to evaluate baseline medication exposures using morphine milligram equivalents (MMEs) and diazepam milligram equivalents (DMEs). In the year following the intervention, we will evaluate changes in medication exposures and medication discontinuations between control and intervention clinics. Incident falls will be evaluated as a secondary outcome. To date, the study has enrolled 914 chronic opioid users and 1048 chronic BZD users. We anticipate that we will have 80% power to detect a 30% reduction in MMEs or DMEs.

Discussion

This clinic randomized pragmatic trial will contribute valuable evidence regarding the impact of pharmacist interventions to reduce falls in older adults through deprescribing of opioids and BZDs in primary care settings.

High-risk medication in community care: a scoping review

PURPOSE

To review the international literature related to high-risk medication (HRM) in community care, in order to (1) define a definition of HRM and (2) list the medication that is considered HRM in community care.

METHODS

Scoping review: Five databases were systematically searched (MEDLINE, Scopus, CINAHL, Web Of Science, and Cochrane) and extended with a hand search of cited references. Two researchers reviewed the papers independently. All extracted definitions and lists of HRM were subjected to a self-developed quality appraisal. Data were extracted, analysed and summarised in tables. Critical attributes were extracted in order to analyse the definitions.

RESULTS

Of the 109 papers retrieved, 36 met the inclusion criteria and were included in this review. Definitions for HRM in community care were used inconsistently among the papers, and various recurrent attributes of the concept HRM were used. Taking the recurrent attributes and the quality score of the definitions into account, the following definition could be derived: "High-risk medication are medications with an increased risk of significant harm to the patient. The consequences of this harm can be more serious than those with other medications". A total of 66 specific medications or categories were extracted from the papers. Opioids, insulin, warfarin, heparin, hypnotics and sedatives, chemotherapeutic agents (excluding hormonal agents), methotrexate and hypoglycaemic agents were the most common reported HRM in community care.

CONCLUSION

The existing literature pertaining to HRM in community care was examined. The definitions and medicines reported as HRM in the literature are used inconsistently. We suggested a definition for more consistent use in future research and policy. Future research is needed to determine more precisely which definitions should be considered for HRM in community care.

Training and Toolkit Resources to Support Implementation of a Community Pharmacy Fall Prevention Service

Community pharmacies are an ideal setting to manage high-risk medications and screen older adults at risk for falls. Appropriate training and resources are needed to successfully implement services in this setting. The purpose of this paper is to identify the key training, tools, and resources to support implementation of fall prevention services. The service was implemented in a network of community pharmacies located in North Carolina. Pharmacies were provided with onboard and longitudinal training, and a project coach. A toolkit contained resources to collect medication information, identify high-risk medications, develop and share recommendations with prescribers, market the service, and educate patients. Project champions at each pharmacy received a nine-question, web-based survey (Qualtrics) to identify usefulness of the training and resources. The quantitative data were analyzed using descriptive statistics. Thirty-one community pharmacies implemented the service. Twenty-three project champions (74%) completed the post-intervention survey. Comprehensive onboard training was rated as more useful than longitudinal training. Resources to identify high-risk medications, develop recommendations, and share recommendations with prescribers were considered most useful. By providing appropriate training and resources to support fall prevention services, community pharmacists can improve patient care as part of their routine workflow.

Analysis of fall-related adverse events among older adults using the Japanese Adverse Drug Event Report (JADER) database

Background

Falls are a common but serious problem in older adults, and may lead to fractures and bleeding. As many factors, such as medication, aging, and comorbid diseases may simultaneously affect fall-related adverse events (AEs) in older adults, we evaluated the association between fall-related AEs and the use of medication, aging, and comorbid diseases using the Japanese Adverse Drug Event Report (JADER) database.

Methods

We analyzed reports of fall-related AEs associated with α-blockers, diuretics, calcium channel blockers, central nervous system (CNS)-active drugs (opioids, benzodiazepines, hypnotics and sedatives, non-selective monoamine reuptake inhibitors, and selective serotonin reuptake inhibitors (SSRI)) in the JADER database using the reporting odds ratio (ROR). For the definition of falls, we used the Preferred Terms of The Medical Dictionary for Regulatory Activities (MedDRA). We used the association rule mining technique to discover undetected associations, such as potential risk factors.

Results

The JADER database comprised 430,587 reports between April 2004 and November 2016. The RORs (95% CI) of α-blockers, diuretics, calcium channel blockers, opioids, benzodiazepines, hypnotics and sedatives, non-selective monoamine reuptake inhibitors, and SSRIs were 1.63 (1.27–2.09), 0.74 (0.63–0.86), 1.26 (1.15–1.38), 0.93 (0.80–1.07), 1.83 (1.68–2.01), 1.55 (1.12–2.14), 2.31 (1.82–2.95), and 2.86 (2.49–3.29), respectively. From the lift value in the association rule mining, the number of administered CNS-active drugs and patient age were associated with fall-related AEs. Furthermore, the scores of lift for patients with herpes zoster administered calcium channel blockers or benzodiazepines and patients with dementia administered benzodiazepines were high.

Conclusion

Our results suggest that the number of administered CNS-active drugs and patient age are both associated with fall-related AEs. We recommend that patients with herpes zoster treated with calcium channel blockers and benzodiazepines be closely monitored for fall-related AEs.

Management of Subdural Hematomas: Part I. Medical Management of Subdural Hematomas

PURPOSE OF REVIEW

Subdural hematomas (SDH) represent common neurosurgical problem associated with significant morbidity, mortality, and high recurrence rates. SDH incidence increases with age; numbers of patients affected by SDH continue to rise with our aging population and increasing number of people taking antiplatelet agents or anticoagulation. Medical and surgical SDH management remains a subject of investigation.

RECENT FINDINGS

Initial management of patients with concern for altered mental status with or without trauma starts with Emergency Neurological Life Support (ENLS) guidelines, with a focus on maintaining ICP < 22 mmHg, CPP > 60 mmHg, MAP 80-110 mmHg, and PaO₂ > 60 mmHg, followed by rapid sequence intubation if necessary, and expedited acquisition of imaging to identify a space-occupying lesion. Patients are administered anti-seizure medications, and their antiplatelet medications or anticoagulation may be reversed if neurosurgical interventions are anticipated, or until hemorrhage is stabilized on imaging. Medical SDH care focuses on (a) management of intracranial hypertension; (b) maintenance of adequate cerebral perfusion; (c) seizure prevention and treatment; (d) maintenance of normothermia, eucarbia, euglycemia, and euvolemia; and (e) early initiation of enteral feeding, mobilization, and physical therapy. Post-operatively, SDH patients require ICU level care and are co-managed by neurointensivists with expertise in treating increased intracranial pressure, seizures, and status epilepticus, as well as medical complications of critical illness. Here, we review various aspects of medical management with a brief overview of pertinent literature and clinical trials for patients diagnosed with SDH.

Medication use and falls: Applying Beers criteria to medication review in Parkinson's disease

Objectives:

Our goal was to assess the association between potentially inappropriate medication use and risk of falls in the Parkinson’s disease population.

Methods:

This was a retrospective cohort study conducted at an outpatient Parkinson’s Disease Treatment Center. Individuals 65 years of age or older, diagnosed with Parkinson’s disease who attended at least three visits in 2015 for physical, occupational therapy, or physician’s visits were included in the study. Electronic medical records were utilized to perform chart reviews, and medications were analyzed to identify prescription medications, combination preparations, over-the-counter medications, and dietary supplements. The goal of this study was to test the following hypothesis: elderly individuals with Parkinson’s disease who take multiple potentially inappropriate medications are more likely to experience a fall compared to elderly individuals with Parkinson’s disease who do not take multiple potentially inappropriate medications.

Results:

A higher mean number of prescription medications were associated with falls in elderly Parkinson’s disease patients (6.53 vs 5.21, p < 0.01). Polypharmacy (taking five or more prescription and nonprescription medications) was not significantly associated with falls. Patients taking potentially inappropriate medications specifically contraindicated for those with a history of falls and fractures were more likely to report falls (p < 0.04). Analysis of the specific therapeutic medication categories demonstrated no significant differences between those who did and did not report falls.

Conclusion:

A future prospective study at Parkinson’s disease center should include an electronic medical record–based intervention to reduce the total number of medications, as well as to minimize the use of high-risk medications.

Impact of a medication therapy management intervention targeting medications associated with falling: Results of a pilot study

BACKGROUND

The use of fall risk-increasing drugs (FRIDs) by older adults is one factor associated with falling, and FRID use is common among older adults. A targeted medication therapy management intervention focused on FRID use that included prescription and over-the-counter (OTC) medications, along with follow-up telephone calls was designed.

OBJECTIVE

The purpose of this pilot study was to examine preliminary effects of a medication therapy management (MTM) intervention focused on FRIDs provided by a community pharmacist to older adults.

DESIGN

Randomized, controlled trial.

SETTING

One community pharmacy.

PARTICIPANTS

Eighty older adults who completed a fall prevention workshop.

MAIN OUTCOME MEASURES

The main outcome measures were the rate of discontinuing FRIDs, the proportion of older adults falling, and the number of falls. A secondary outcome was the acceptance rate of medication recommendations by patients and prescribers.

RESULTS

Thirty-eight older adults received the targeted MTM intervention. Of the 31 older adults using a FRID, a larger proportion in the intervention group had FRID use modified relative to controls (77% and 28%, respectively; P < 0.05). There were no significant changes between the study groups in the risk and rate of falling. Medication recommendations in the intervention group had a 75% acceptance rate by patients and prescribers.

CONCLUSION

A targeted MTM intervention provided by a community pharmacist and focused on FRID use among older adults was effective in modifying FRID use. This result supports the preliminary conclusion that community pharmacists can play an important role in modifying FRID use among older adults.

Effects of drug pharmacokinetic/pharmacodynamic properties, characteristics of medication use, and relevant pharmacological interventions on fall risk in elderly patients

BACKGROUND

Falls among the elderly are an issue internationally and a public health problem that brings substantial economic and quality-of-life burdens to individuals and society. Falls prevention is an important measure of nursing quality and patient safety. Numerous studies have evaluated the association of medication use with fall risk in elderly patients. However, an up-to-date review has not been available to summarize the multifaceted pharmaceutical concerns in the prevention of medication-related falls.

MATERIALS AND METHODS

Relevant literature was identified by performing searches in PubMed, Web of Science, and the Cochrane Library, covering the period until February 2014. We included studies that described an association between medications and falls, and effects of drug pharmacokinetic/pharmacodynamic properties, characteristics of medication use, and pharmacological interventions on fall risk in elderly patients. The full text of each included article was critically reviewed, and data interpretation was performed.

RESULTS

Fall-risk-increasing drugs (FRIDs) include central nervous system-acting agents, cough preparations, nonsteroidal anti-inflammatory drugs, anti-Alzheimer's agents, antiplatelet agents, calcium antagonists, diuretics, α-blockers, digoxin, hypoglycemic drugs, neurotoxic chemotherapeutic agents, nasal preparations, and antiglaucoma ophthalmic preparations. The degree of medication-related fall risk was dependent on one or some of the following factors: drug pharmacokinetic/pharmacodynamic properties (eg, elimination half-life, metabolic pathway, genetic polymorphism, risk rating of medications despite belonging to the same therapeutic class) and/or characteristics of medication use (eg, number of medications and drug-drug interactions, dose strength, duration of medication use and time since stopping, medication change, prescribing appropriateness, and medication adherence). Pharmacological interventions, including withdrawal of FRIDs, pharmacist-conducted clinical medication review, and computerized drug alerts, were effective in reducing fall risk.

CONCLUSION

Based on the literature review, clear practical recommendations for clinicians to prevent falls in the elderly included making a list of FRIDs, establishing a computerized alert system for when to e-prescribe FRIDs, seeking an alternative drug with lower fall risk, withdrawing FRIDs if clinically indicated, taking pertinent cautions when the use of FRIDs cannot be avoidable, paying attention to prescribing appropriateness, simplifying the medication regimen, strengthening pharmacist-conducted clinical medication review, ensuring the label of each FRID dispensed contains a corresponding warning sign, being careful when medication change occurs, enhancing medication adherence, and mandating for periodic reassessment of potential risk associated with the patient's medication regimen. Further studies should be conducted in this area, such as investigating whether medication reconciliation and improving medication adherence could decrease the rate of falls.

Interventions for preventing falls in older people living in the community

BACKGROUND

Approximately 30% of people over 65 years of age living in the community fall each year. This is an update of a Cochrane review first published in 2009.

OBJECTIVES

To assess the effects of interventions designed to reduce the incidence of falls in older people living in the community.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (February 2012), CENTRAL (The Cochrane Library 2012, Issue 3), MEDLINE (1946 to March 2012), EMBASE (1947 to March 2012), CINAHL (1982 to February 2012), and online trial registers.

SELECTION CRITERIA

Randomised trials of interventions to reduce falls in community-dwelling older people.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data. We used a rate ratio (RaR) and 95% confidence interval (CI) to compare the rate of falls (e.g. falls per person year) between intervention and control groups. For risk of falling, we used a risk ratio (RR) and 95% CI based on the number of people falling (fallers) in each group. We pooled data where appropriate.

MAIN RESULTS

We included 159 trials with 79,193 participants. Most trials compared a fall prevention intervention with no intervention or an intervention not expected to reduce falls. The most common interventions tested were exercise as a single intervention (59 trials) and multifactorial programmes (40 trials). Sixty-two per cent (99/159) of trials were at low risk of bias for sequence generation, 60% for attrition bias for falls (66/110), 73% for attrition bias for fallers (96/131), and only 38% (60/159) for allocation concealment.Multiple-component group exercise significantly reduced rate of falls (RaR 0.71, 95% CI 0.63 to 0.82; 16 trials; 3622 participants) and risk of falling (RR 0.85, 95% CI 0.76 to 0.96; 22 trials; 5333 participants), as did multiple-component home-based exercise (RaR 0.68, 95% CI 0.58 to 0.80; seven trials; 951 participants and RR 0.78, 95% CI 0.64 to 0.94; six trials; 714 participants). For Tai Chi, the reduction in rate of falls bordered on statistical significance (RaR 0.72, 95% CI 0.52 to 1.00; five trials; 1563 participants) but Tai Chi did significantly reduce risk of falling (RR 0.71, 95% CI 0.57 to 0.87; six trials; 1625 participants).Multifactorial interventions, which include individual risk assessment, reduced rate of falls (RaR 0.76, 95% CI 0.67 to 0.86; 19 trials; 9503 participants), but not risk of falling (RR 0.93, 95% CI 0.86 to 1.02; 34 trials; 13,617 participants).Overall, vitamin D did not reduce rate of falls (RaR 1.00, 95% CI 0.90 to 1.11; seven trials; 9324 participants) or risk of falling (RR 0.96, 95% CI 0.89 to 1.03; 13 trials; 26,747 participants), but may do so in people with lower vitamin D levels before treatment.Home safety assessment and modification interventions were effective in reducing rate of falls (RR 0.81, 95% CI 0.68 to 0.97; six trials; 4208 participants) and risk of falling (RR 0.88, 95% CI 0.80 to 0.96; seven trials; 4051 participants). These interventions were more effective in people at higher risk of falling, including those with severe visual impairment. Home safety interventions appear to be more effective when delivered by an occupational therapist.An intervention to treat vision problems (616 participants) resulted in a significant increase in the rate of falls (RaR 1.57, 95% CI 1.19 to 2.06) and risk of falling (RR 1.54, 95% CI 1.24 to 1.91). When regular wearers of multifocal glasses (597 participants) were given single lens glasses, all falls and outside falls were significantly reduced in the subgroup that regularly took part in outside activities. Conversely, there was a significant increase in outside falls in intervention group participants who took part in little outside activity.Pacemakers reduced rate of falls in people with carotid sinus hypersensitivity (RaR 0.73, 95% CI 0.57 to 0.93; three trials; 349 participants) but not risk of falling. First eye cataract surgery in women reduced rate of falls (RaR 0.66, 95% CI 0.45 to 0.95; one trial; 306 participants), but second eye cataract surgery did not.Gradual withdrawal of psychotropic medication reduced rate of falls (RaR 0.34, 95% CI 0.16 to 0.73; one trial; 93 participants), but not risk of falling. A prescribing modification programme for primary care physicians significantly reduced risk of falling (RR 0.61, 95% CI 0.41 to 0.91; one trial; 659 participants).An anti-slip shoe device reduced rate of falls in icy conditions (RaR 0.42, 95% CI 0.22 to 0.78; one trial; 109 participants). One trial (305 participants) comparing multifaceted podiatry including foot and ankle exercises with standard podiatry in people with disabling foot pain significantly reduced the rate of falls (RaR 0.64, 95% CI 0.45 to 0.91) but not the risk of falling.There is no evidence of effect for cognitive behavioural interventions on rate of falls (RaR 1.00, 95% CI 0.37 to 2.72; one trial; 120 participants) or risk of falling (RR 1.11, 95% CI 0.80 to 1.54; two trials; 350 participants).Trials testing interventions to increase knowledge/educate about fall prevention alone did not significantly reduce the rate of falls (RaR 0.33, 95% CI 0.09 to 1.20; one trial; 45 participants) or risk of falling (RR 0.88, 95% CI 0.75 to 1.03; four trials; 2555 participants).No conclusions can be drawn from the 47 trials reporting fall-related fractures.Thirteen trials provided a comprehensive economic evaluation. Three of these indicated cost savings for their interventions during the trial period: home-based exercise in over 80-year-olds, home safety assessment and modification in those with a previous fall, and one multifactorial programme targeting eight specific risk factors.

AUTHORS' CONCLUSIONS

Group and home-based exercise programmes, and home safety interventions reduce rate of falls and risk of falling.Multifactorial assessment and intervention programmes reduce rate of falls but not risk of falling; Tai Chi reduces risk of falling.Overall, vitamin D supplementation does not appear to reduce falls but may be effective in people who have lower vitamin D levels before treatment.

Implementation of a community pharmacy-based falls prevention program

BACKGROUND

Falls are the leading cause of fatal and nonfatal unintentional injury among older adults in the United States. Multifaceted falls prevention programs, which have been reported to reduce the risk for falls among older adults, usually include a medication review and modification component. Based on a literature search, no randomized trials that have examined the effectiveness of this component have been published.

OBJECTIVE

The aim of this article was to report on a retrospective process evaluation of data from a randomized, controlled trial conducted to examine the effectiveness of a medication review intervention, delivered through community pharmacies, on the rate of falls among community-dwelling older adults.

METHODS

Patients were recruited through 32 pharmacies in North Carolina. Participants were community-dwelling older adults at high risk for falls based on age (≥ 65 years), number of concurrent medications (≥ 4), and medication classes (emphasis on CNS-active agents). The process evaluation measured the recruitment of patients into the study, the process through which the intervention was delivered, the extent to which patients implemented the recommendations for intervention, and the acceptance of pharmacists' recommendations by prescribing physicians.

RESULTS

Of the 7793 patients contacted for study participation, 981 (12.6%) responded to the initial inquiry. A total of 801 (81.7%) participated in an eligibility interview, of whom 342 (42.7%) were eligible. Baseline data collection was completed in 186 of eligible patients (54.4%), who were randomly assigned to the intervention group (n = 93) or the control group (n = 93). Pharmacists delivered a medication review to 73 of the patients (78.5%) in the intervention group, with 41 recommendations for changes in medication, of which 10 (24.4%) were implemented. Of the 31 prescribing physicians contacted with pharmacists' recommendations, 14 (45.2%) responded, and 10 (32.3%) authorized the changes.

CONCLUSIONS

Based on the findings from the present study, coordination of care between community pharmacists and prescribers needs to be improved for the realization of potential beneficial effects of medication management on falls prevention.

The surgical management of chronic subdural hematoma

Chronic subdural hematoma (cSDH) is an increasingly common neurological disease process. Despite the wide prevalence of cSDH, there remains a lack of consensus regarding numerous aspects of its clinical management. We provide an overview of the epidemiology and pathophysiology of cSDH and discuss several controversial management issues, including the timing of post-operative resumption of anticoagulant medications, the effectiveness of anti-epileptic prophylaxis, protocols for mobilization following evacuation of cSDH, as well as the comparative effectiveness of the various techniques of surgical evacuation. A PubMed search was carried out through October 19, 2010 using the following keywords: "subdural hematoma", "craniotomy", "burr-hole", "management", "anticoagulation", "seizure prophylaxis", "antiplatelet", "mobilization", and "surgical evacuation", alone and in combination. Relevant articles were identified and back-referenced to yield additional papers. A meta-analysis was then performed comparing the efficacy and complications associated with the various methods of cSDH evacuation. There is general agreement that significant coagulopathy should be reversed expeditiously in patients presenting with cSDH. Although protocols for gradual resumption of anti-coagulation for prophylaxis of venous thrombosis may be derived from guidelines for other neurosurgical procedures, further prospective study is necessary to determine the optimal time to restart full-dose anti-coagulation in the setting of recently drained cSDH. There is also conflicting evidence to support seizure prophylaxis in patients with cSDH, although the existing literature supports prophylaxis in patients who are at a higher risk for seizures. The published data regarding surgical technique for cSDH supports primary twist drill craniostomy (TDC) drainage at the bedside for patients who are high-risk surgical candidates with non-septated cSDH and craniotomy as a first-line evacuation technique for cSDH with significant membranes. Larger prospective studies addressing these aspects of cSDH management are necessary to establish definitive recommendations.

Impact of enhanced pharmacologic care on the prevention of falls: a randomized controlled trial

BACKGROUND

Falls are the leading cause of both fatal and nonfatal injuries among older adults in the United States. Medications that affect the central nervous system are known to increase the risk of falling.

OBJECTIVE

The purpose of this study was to assess the effects of a community pharmacy-based falls-prevention program targeting high-risk older adults on the rates of recurrent falls, injurious falls, and filling prescriptions for medications that have been associated with an increased risk of falling.

METHODS

This was a randomized controlled trial of participants recruited through a community pharmacy chain in North Carolina. The 2-year study consisted of a 1-year "look-back" period before randomization and a 1-year follow-up period after randomization. Patients were eligible to participate if they were ≥65 years of age, had fallen at least once during the 1-year period preceding enrollment, and were taking medications associated with an increased risk of falling. Medications classified as high risk included benzodiazepines, antidepressants, anticonvulsants, sedative hypnotics, opioid analgesics, antipsychotics, and skeletal muscle relaxants. Participants were assigned to either the intervention arm or the control arm; participants in the intervention arm were invited to attend a face-to-face medication consultation conducted by a community pharmacy resident, whereas those in the control arm received no medication consultation. The primary end point was the rate of recurrent falls during the 1-year followup period. Secondary end points were the total number of prescriptions for high-risk medications filled during the follow-up period and either discontinued use or a reduction in the dosage of a high-risk medication during the follow-up period.

RESULTS

One hundred eighty-six patients (132 women, 54 men; 88.7% white) were enrolled. Intention-to-treat (ITT) analyses revealed no significant differences in the rates of recurrent falls, injurious falls, or filling prescriptions for high-risk medications. However, 13 patients in the intervention group either discontinued use of a high-risk medication or had the dosage reduced during the follow-up period, compared with 5 patients in the control group (χ(2) = 3.94; P < 0.05). As-treated analyses revealed numeric reductions in the rates of falls (rate ratio [RR] = 0.76; 95% CI, 0.53-1.09), injurious falls (RR= 0.67; 95% CI, 0.43-1.05), and filling prescriptions for high-risk medications (RR= 0.85; 95% CI, 0.72-1.03) after receipt of the intervention, but the differences were not statistically significant.

CONCLUSIONS

Results of this study support the feasibility of using community pharmacies to deliver a falls-prevention program targeting high-risk older adults. Although the ITT analyses revealed no significant reduction in the rate of recurrent falls, injurious falls, or overall use of high-risk medications, individuals in the intervention group were more likely than those in the control group to discontinue use of a high-risk medication or have the dosage reduced during the 1-year follow-up period. More work is needed to evaluate the intervention using a larger sample size that provides greater power to detect clinically meaningful effects of reduction in the use of high-risk medications on preventing or reducing falls in the high-risk population.
